I am not sure what kind of front panel that is - how to indicate that? The problem is that I can't access the back connector of the front panel that easily without deconstructing almot the whole system...

If I get that right, HD audio and AC97 plug into the same connector, so the cable is in the right spot either ways, isn't it?

Cable's in the right spot, but can't tell from looking at it whether it is AC97 or HD Audio. If you don't have it check your case manufacturer's site for the manual and hopefully it will say which it is supposed to be.

You've set the Front panel type to AC97, as mentioned.
You probably need to install the Realtek AC97 codec software.
I'm not sure if you can use it with the Realtek HD Audio software, so you may need to uninstall it.

You may be able to use both codecs together or it may be one of those either/or situations.
I don't know.
Good Luck!

Doesn't work that way, the onboard audio still needs the HD driver. The only reason for that option in the bios is so that the fpaudio connectors on the motherboard can be connected to the front panel audio on the case regardless of how the case is wired.

Don't have anything here that has Realtek audio but found this elsewhere,

Try it by matching that setting with the one in the bios until you hit the combo that works.

On my case the cable from the front panel audio jacks has two plugs on it. One is AC97 and the other is HD Audio, each one is wired different. I have to match the BIOS setting to the plug I use.
This might help.AC'97 and HD audio front panel layouts

EDIT: If you can look though the manual fro your motherboard and see if it gives the pin out for the audio header. Then do the same thing with your case manual and compare the two to see if they match.
